IntEnz Enzyme Nomenclature
EC 1.14.19.37

Names

Accepted name:
acyl-CoA 5-desaturase
Other name:
acyl-CoA 5-desaturase (non-methylene-interrupted)
Systematic name:
acyl-CoA,acceptor:oxygen oxidoreductase (5,6 cis-dehydrogenating)

Reactions

Comments:

The enzyme, characterized from the plant Anemone leveillei, introduces a cis double bond at carbon 5 of acyl-CoAs that do not contain a double bond at position 8. In vivo it forms non-methylene-interrupted polyunsaturated fatty acids such as sciadonate and juniperonate. When expressed in Arabidopsis thaliana the enzyme could also act on unsaturated substrates such as palmitoyl-CoA. cf. EC 1.14.19.44 acyl-CoA (8-3)-desaturase.
